To all-.whom it may concern:

Be it knownthat I, J oHNH. '\VALL,L citizen-of the- United States, residing-at Bristol, in -the county of Bristol and State of Rhode Island, have invented ashoesand more particularly to an improvement in machines adapted to dip or varnish rubber shoes.

The object of. my invention is tosimprove the con--- struction of a shoe dipping or varnishing machine whereby the-operation of dipping'or varnishing a plu rality of rubber shoes and thehan dlingof thesamearefacilitated.

A further object of my invention is to increase-the product of a shoe dipping or varnishing machine and simultaneously to allow the shoes to drip therequired length of time-beforeremovalfrom the machine.

My invention consists in the peculiar and novel. con-- structionof a shoe dipping-machine adapted to dip or varnishia plurality. ofrubber' shoes, to automatically hold the shoes in the machine therequiredlength of.

time to drip, and havingdetails-of construction as-will be-more fully set forth hereinafter and claimed.

The frame a consists-of the end frames, 8 8, having the vertical extensions 9 9 at therear, the bearings 10 10 and 11 11 in the lower portion of the framefor the driving and crank shafts b and c, the bearings 12 12 placed centrally in the vertical extensions 9 9 for the rock shalt d, the bearings 13' 13 at the top of the vertical extensions 9 9 for the rock shaft 0, the cross struts 14- 14 onthe end frames supporting the varnish tank f, and the fixed brackets 15 15 at each end of the tank, each bracket having a notch 16,-as shown in Figs. 1 and 2.

The driving shaft 1) isrotatably supported in the bearings 10-10-andhas a driving pulley l7 and a pinion l8 meshing with a gear 19 on the crank shaft 0 which has a crank 20, as shown in Fig. 2.

The varnish tank f is rectangular in forms It ex-' tends the length of the frame-on the cross struts l4 l4 and has an inclined front and back 2] and 22; a flat bottom 23 and, the ends 24 24 shaped to (oniorin to the front, back and bottom, asshown in Figs. 2 and 3.

The loweringand elevating lever g is secured at its rear end centrally to the rock shaft (I. This lever extends under and then upward in front of the varnish tank f to bring the handle 25 in a convenient position for the operator and is bent to conform to the shapeol' theitank, as shown in Fig. 2.

The weight lever [1V is secured to therock shaft (1 and has a weight 26., as shown in Fig. 2, adapted to slightly overbalance the weight of the arnisk la, the rotating mechanism 1,, therotating levers m m, the lowering and elevatinglever g, thepeg bar 7), the lasts r r, and the shoes .9 s on the lasts.

Theweight lever i is secured to the rock shaft e and has a weight 27 adapted to slightly overbalancc the weight of the automatic dripping mechanism a with the peg bar p, the lasts 7' r and the shoes s s on the-lasts, as shown in Fig. 2.

The rotating mechanism supporting arms I: k are socured to the rock shaft (1 at each end and extendover the varnish tank f, as shown in Fig. 2.

The rotating mechanism. Z consists of bearings 28 2S formed'on the forward ends of the arms k it, an opening 29in the end of each arm extending through thebearing 28, a semicircular lip 30 on the inner-face of each arm formed slightly eccentric with the bearing and with the ends in an upward position, a curved lip on the inner face of each arm adjacent the semi-circular lip 30 and forming a stop. 31, a shaft 32 in each bearing 28 and having formed on itsv innerend a member 33 constructed to have an elongated transverse recess 34 with the closed end 35-and the open end SGfor theends of the peg bar p and an arm 37 extending downward from the member in a position to engage with the stop 31., when the rotating mechanismv is in its normalposition, an arm 38 pivotally secured to the end of each of the arms 37 37, a round locking bar 39 secured at each end to the free ends of the-arms 38 38 or formed integral therewith, a flexible cord 40 secured to the bar and extending upwards over a grooved pulley 41 rotatahly supported on the rock shaft e, and then down to a coiled spring 42 secured at one end to the cord 40 and at the other end to the weight 26, the tension of the coiled spring 42 holding the arms 38 38 in contact with the.

of the rotating mechanism 1 in the openings 29 29 in the ends of the arms k k. The rotating levers m m, the cross bar 44 and the arms 45 45 are all formed integral, as shown in Figs. 1 and 4. The fixed brackets 1.5 15 are placed at each end of the machine in a position for the ends 43 43 of the rotating levers to enter the notches 16 16 in the brackets and hold the operative mechanism in its raised or normal position, as shown in Fig. 2.

The automatic dripping mechanism n consists of a locking lever 46 secured centrally to the rock shaft 6 in approximately a horizontal position and having a bev- 01 ed vertical hole 47 adjacent its free end, a spring bolt 48 secured to the underside of the lever in a position for the end of the bolt to extend across the hole 47, as shown in Fig. 6, a vertical rod 49 having the transverse hole 50 adjacent its upper end for the bolt 48 and pivotally secured at its lower end to the crank 20 in a position for the rod to extend upward through the hole 47 in the lever 46, as shown in Fig. 2, two end levers 51 51 secured to the rock shaft e, vertical arms 52 52 each pivotally secured at its upper end to the end of each of the levers 51 51 and each having-a hook-shaped lower end 53 forming a beveled edge 54 on the lower end of the arm, a cross bar 55 connecting the arms 52 52, a cord 56 connecting the bar 55 with the spring bolt- 48 and a hand lever 57 secured to the rock shaft e and extending forward over the varnish tank f in a convenient position for the operator, as shown in Fig. 2.

The weight standard 0 consists of a vertical rod 58 having the brackets '59 and 60 and secured to the floor at the rear of the machine by the base 61 in a position for the bracket 59 to support the weight 26 on the lever 71 and for the bracket 60 to support the weight 27 on the lever 4', as shown in Fig. 2.

The peg bar 7) has a series of pegs 62 62 extending out ward from the rear face of the bar in sets of two, one set for each last. These pegs enter coinciding holes in the top of the lasts (not shown) and hold the lasts on the bar.

In the operation of my improved shoe dipping or varnishing machine, the tank f is filled with varnish or a similar liquid to approximately a height, as shown in Fig. 3. Power is applied to the driving pulley 17 in the usual way to revolve the crank 20 and give a constant reciprocating motion to the vertical rod 49 through the hole 47 in the locking lever 46 of the dripping mechanism 11. The weight of the varnished shoes and lasts in the dripping mechanism n moves the arms 52 52 forward into the position as shown in full lines in Fig. 2, and through the cord 56 holds the bolt 48 out of engagement with the rod 49 against the tension of the spring on the bolt. A peg bar 1) with the lasts and shoes is placed in the machine with the ends of the bar in the recesses 34 34 in the rotating mechanism Z with the shoes in a position intermediate the peg bar p and the locking bar 39 and with the toes of the shoes extending downward, as shown in Fig. 2. The operator now grasps the handle 25 of the lowering and elevating lever g with his left hand, a rotating lever m with his right hand and by a slight upward movement of his right hand releases the end 43 of the rotating lever from the notch 16 in the bracket 15. The lowering and elevating lever g is now depressed and simultaneously the rotating lever m given a forward and upward movement, thus operating the rotating mechanism Z to partly revolve the peg bar p, the lasts 1' r, and the shoes 8 s to submerge the shoes in the varnish in the tank f, as'shown in Fig. 3. As the rotating mechanism Z starts to revolve the locking bar 39 comes into engagement with the heels of the shoes by the tension of the spring 42 on the cord 40, and the arms 38 38 leave the stops 31 31. The locking bar 39 is now held against the heels of the shoes by the tension of the spring 42, thereby locking the lasts and shoes to the peg bar in the operation of dipping the shoes. The peg bar p is locked when in the dipping position in the recesses 34 34 by the semi-circular lips 30 30 on the arms is is closing over the open ends 36 36 of the recesses 34 34, as shown in Fig. 3. On the reverse movement of the levers g and m the mechanism resumes its normal position, the ends 43 43 of the levers 'm m are snapped into the notches 16 16 in the brackets 15 15 and the locking bar 39 leaves the heels of the shoes by, the arms 38 38 coming into engagement with the stops 31 31 on the arms It It. The operator now removes the peg bar with the varnished shoes from the dripping mechanism n by an upward and a forward movement of the peg bar. When the bar and shoes are removed from the arms 52 52, these arms move back by the force of gravity and the tension of the spring on the bolt 48 into the position as shown in broken lines in Fig. 2, releasing the bolt 48, which on the downward movement of the rod 49 enters the hole 50 in the rod and locks the arm 46 to the rod 49. The next upward movement of the rod 4-9 depresses the lovers 5]. 51, the beveled edges 54 54 on the ends of the arms 52 52 strike the upper edge of the peg bar p in the rotating mechanism Z, forcing the hook shaped ends 53 53 back of the peg bar and allowing the same to come under the ends of the peg bar when, on the next downward movement of the rod 49, the peg bar and shoes are lifted out of the rotating mechanism by the arms 52 52 into the position, as shown in full lines in Fig. 2, when the weight of the shoes and lasts moves the arms 52 52 forward and through the cord 56 pulls the bolt 48 out of engagement with the rod 49. The shoes are now held in the dripping mechanism n for a sufficient length of time and in a position for the excess of varnish to drip off the toes of the shoes into the varnish tank f. The operator now places a peg bar Having thus described my invention, I claim as new and desire to secure by Letters Patent;-
